Cleaning the Main Brushes
It is important that you regularly remove and clean the Brushes of your Roomba. Debris
can accumulate around the Brushes and the brush ends, or axles, causing a decrease in
cleaning ability and potentially damaging the unit.
In most households it's a good idea to clean the Brushes after every ten floor cleanings.
In houses with pets or long hair, clean the Brushes after every five floor cleanings. Note that
the Cleaning Brush axles cannot be checked without removing the Brushes from Roomba. It
is a simple process that you will master quickly with a little practice.
Figure 12a-b: Unlatch the Wire Guards by pushing each of the two Release Tabs
forward (away from you) while pushing down on the Wire Guards to elongate them,
swinging the Wire Guards up and over the tabs. Once the Wire Guard has been freed
from both Release Tabs, it can be swung up and away, exposing the Brushes.
1. Turn Roomba's Main Power Switch off and place Roomba upside down
(cleaning surface up) on a flat surface, with the Front Bumper facing away from you.
2. Unlatch the Wire Guards that cover the Brushes by pushing the Release Tab backward
(see Figure 12a). Pull the rear of the hinged Wire Guards up and out of their slots, and
then swing them up toward the front of the device (Figure 12b).
Figure 12c-d: Remove the screw on the Self-Adjusting Cleaning Deck and pull out
the plastic Brush Coupler and the two Brushes.
3. Unscrew the screw located on the right side of the Self-Adjusting Cleaning Deck with a
Phillips-head screwdriver (Figure 12c). Remove the screw and pull up the Brush Coupler
(see inset in Figure 12d), the component that holds the Brushes in place on the right side
of the unit. The Brushes will come up with the Brush Coupler.

4. Pull the Brush Coupler off the end of the Brushes, then pull the Brushes to the
right and up, free of the device (Figure 12d).
5. Clean any hair or other debris off the
Brushes.
6. Clean any debris from around the
Brush ends, or axles (Figure 13).

built up or wound around the ends and
metal axles of both Brushes.
Reassembling the Brushes
1. Put the Self-Adjusting Cleaning Deck back together by inserting the square ends of
the two Brushes into the square sockets in the Cleaning Deck.
2. Insert the other ends of the Brushes into the small holes in the Brush Coupler.
3. Lower the Brush Coupler into its slot and screw in the screw.
4. Swing the Wire Guards back in place and snap them down into their slots.
Maintaining the Edge-Cleaning Side Brush
Periodically check the Edge-Cleaning Side Brush by spinning it to ensure debris has
not built up underneath it. If it seems to be obstructed, remove and clean the
Edge-Cleaning Side Brush.
1. Turn Roomba off and empty the Particle Bin. Turn Roomba over so the cleaning
surface is up. Place it on a flat surface.
2. Turn the Edge-Cleaning Side Brush so the Screw Head can be accessed (see Figure 14).
Point the screw head towards Roomba's bumper, as shown in the image.
3. Using a small Phillips-head screwdriver, unscrew the holding screw.
Place the screw aside.
4. Pull the Side Brush up and off of Roomba.
5. Clean out any hair or other debris that may have been caught under the Brush
or on the Side Brush Shaft.
6. Push the Side Brush back onto the Side Brush Shaft. Screw the holding screw securely
into the Edge-Cleaning Side Brush, being careful not to over tighten.
